Smiley face mouse icon in MATLAB

I was plotting some graph in MATLAB (R14) and was using the Show/Hide Plot Tool button.
When I toggled between show and hide plot, suddenly the mouse pointer become a smiley face!!!



I later found that I need to use the Rotate 3D function first, then toggle show and hide plot for it to happen. Is it an easter egg in Matlab? It's funny.

In order to get this screenshot, I tried to use PrintScreen but the very mouse cursor that I want is not included in the captured image. So I did a quick search and found ACA Capture, a shareware that does the job.
More screen capture softwares can be found on download-by.net.
